This should be mandatory watching for almost (see below) every human being alive today. But especially for almost all parents and children, mechanchim and talmidim.
Note: See the comments for the criticisms which caused me to introduce the bold caveats above. This is a public television video, and it does contain a very brief display of a scantily clad female teenager (as part of a cautionary segment concerning what parents discover concerning their children's internet activity). If this scene is something that would prevent you from viewing a video, ashrecha! You are lucky to be part of the very small portion of today's society who may not be subject to most of the pitfalls that the overwhelming majority of even the most Orthodox Jewish society faces today.
